Hello,
I am having trouble sorting out this annoying image noise problem.

Full disclosure: I am NOT a professional. Im a DSLR Guy and I just want to make some cool stuff. I posted a whole spiel in general discussion about how Im probably in over my head here. But I guess its ok for me to post my idiotic question as long as its in the right area. So Im throwing myself out there. Because Im desperate.

So here it is. I have learned about various lighting techniques and Ive tried to apply them, but no matter what I do I cant seem to shake this noisy/grainy crap in my footage. Sometimes its a little more subtle. But when Im editing and I see it, I cant NOT see it. It gnaws at me and irritates me to no end.

So Im doing some tests...going for a darker dramatic look (in my living room). I have a practical light (a lamp), a key light, and I also mess around with a fill light. It looks ok when shooting it...really dark and moody. But once I drop it into my editing software, there it is. Garbage.

I watch a lot of YouTubethe guys over at Film Riot for exampleAnd of course their footage is always clean and sharp looking. I put this light here, and do this, and place a fill light here...
Oh look how easy that is! Let me try. And then I jack it all up.

My ISO never excess 200, I use pretty fast lenses, and (to my knowledge) the exposure is alright. People in other forums have been nice enough to school me on nailing exposure and stuff. I have learned a lot. But Im obviously still coming up short.

Even when theres a lot of light, I can still see it...like in my gray couch.

What other variables could there be? My cheap POS camera maybe? Ive seen clean video shot with cameras in the same class.

Im just really frustrated.

Thanks in advance to anybody who has the time to entertain this.

Probably easier done on something other than a phone.

 

Two options. Upload them somewhere and link to them from here, or upload them here as attachments.

As anyone else already said, please upload some pictures.

 

Besides that, what camera do you have? 200 ISO is not a lot, but at the same time, every camera has some ISOs that works better than another. Please specify the model of the camera, what lens and what f/stop you are using.

 

 

Bye!

Here is a clip I have. I was testing to see just how the lighting worked. Focus is bad, as I wasn't really able to pull it off with just myself. 

 

Shot with Canon 1200D (Rebel T5), Rokinon "cine" lens (35mm), aperture pretty much wide open at 1.5, ISO at 100. Also, I use that Cinestyle profile that you install on Canon cameras. 

 

Shutter speed 50--24 fps

 

It's pretty much a low/no budget DIY show for me, so it's obviously amateur hour here. So any insight is greatly appreciated. 

 

It's a medium(?) shot so the practical light/lamp isn't in frame. I used a cheap clamp light with aluminum reflector from Lowe's--diffused with a 5 in 1 reflector. In this particular test I didn't use fill light (hair lighting...or whatever you call it) I had placed off to my right...but those had the same issues. 

 

Maybe the lights aren't bright enough? Noise due to lack of sharp focus? My cheap camera? I don't know...

You gotta upload it to a 3rd party place. This forum was made in the 90s or something so it's tricky.

I just plopped a couple clips into YouTube. 

 

The second part was made after I messed with curves and stuff. 

look at the couch. Heinous.

Alright, well I guess YouTube makes it look a little different after compressing it and whatnot. 

 

Still looks like garbage...but a different kind of garbage.

What did you light it with?

 

The adjusted version is an improvement, certainly.

A $6.00 clamp light I bought at Lowes. You know, the aluminum ones?

And the first part of the video is the one I color corrected.

Well not corrected per se. But I messed with the curves.

Do you think brighter lights would help reduce noise?

I think the part that I messed with was the most noisey. That couch!

What is the ISO and the f/stop that you used in the video that you uploaded?

 

You have a really decent lens for the camera you have. It's kinda a 50mm because the sensor is 1.6, but it's should look better than that.

 

 

Did you try the lens on f4.5 or 5.6? Because even if the lens can open to 1.5, that doen't mean that is the optimal f stop. The lens usually shine at their best on f stops a little bit higher, like 4.5.

 

Oh, and the last think. You have a expensive lens but really crappy lights. Cinematography is like audio, is a chain and if you have a crappy link, all the chain in front of that is crappy. It's like recording a guitar. If the instrument is bad, all is bad, no matter what console or mics do you have. If the cable of the guitar is bad, even if the guitar is good, you obtain bad sound. If the mic is bad, it doen't matter the preamp or the console, and so on.

 

 

If you want to shot an scene, forget the freaking camera. It doesn't matter if the scene have bad lighs (and if you have good lights but a bad actor, is like a good preamp with a crappy guitar). You need to have a good scene, and then have a good lens, and a good camera, etc.

And the lights are usually cheapers that a good camera or a good lens, but people often miss that, and is a easy mistake to avoid.

I guess my problem is that I only recently started getting into this stuff. My first major purchase was a couple lenses. And Ive been building from there.

I guess I can compare it to my other hobbyhunting and fishing. One of my bows that I hunt with is maybe 200 bucks. Bare. But I have a 240.00 sight on it. I have another bow that probably cost me 1,800 bucks. Its how you use it...as the saying goes.

I use the cheap lights because, apparently, you can still pull off a decent lighting set up with them. People do it. Im just trying to figure out how.

So if I shoot with the aperture at 4.5 or whatever, and it darkens the image, just add more light? The darker the area, the potential for more noise, no?

Maybe I can buy better bulbs? Brighter? I dont really see how the cost of the actual housing would affect quality.

I dont do this for a living so I have to buy the stuff I need a little at a time...as I can afford it.

I read something just a few days ago about how its actually better to (almost) overexpose then to underexpose.

The living room was dark enough, as you could probably see. And that was with two lights. Its not a big room. The second I go higher than f2, it darkens the scene considerably.

So try 4.5 and throw more light in?

Man the first part of that YouTube video doesnt look half bad. But Im viewing it from my phone. Playing the freshly rendered video in QuickTime, on my computer, shows all the ugly crap jittering around in the grays.

The only thing to be a bit cautious about is LED lights. They can have slightly (or very) iffy colour quality that can create problems when you try to achieve certain effects. Cost of the housing doesn't affect quality, it may affect how easy it is to control the light. Happily it's pretty easy to get some styrene insulating board - leave one side white for reflecting light, and paint the other side black to flag it off.

 

Perhaps I misunderstood - what sort of look are you after? If the first sequence is the graded one, it seems like you were after a sort of cool night effect.

Cost of the housing doesn't affect quality.
